gap analysis of Public Transport needs measuring spatial distribution of Public Transport needs and identifying gaps in the quality of Public Transport provision
Transportation Research Record, 2004Co-Authors: Graham CurrieAbstract:A new approach to assessing the performance of Public Transport in meeting the needs of Transport-disadvantaged people in the community is described. It reviews previous and current research in this area and describes how a new approach has been developed and applied with Hobart, Australia, as a study area. The approach aims to identify geographical gaps in Public Transport provision where travel needs are high but services are poor or nonexistent. It involves the use of readily available socioeconomic statistics to quantify the distribution of needs in the community with a single Transport needs index. A Public Transport network model measures the Public Transport accessibility to these groups and a geographical information systems approach is used to display the distribution of the identified gaps between service and needs. The technique is highly relevant for smaller urban centers where the justification of Public Transport subsidies is largely social-needs-based—that is, where congestion and environme...

Application of WebGIS in the intelligent Public Transport dispatching system In Intelligent Public Transport Dispatching System
Technology and Economy in Areas of Communications, 2020Co-Authors: Liu Guang-mingAbstract:It introduces briefly the concept and the systematic composition of intelligent Public Transport dispatching system as well as the concept of WebGIS. Combined the characteristics of the intelligent Public Transport dispatching system with those available, it also discusses the theories and realization methods of Public Transport information searching system and Public Transport vehicle monitoring and dispatching system based on WebGIS.

Subsidies in Public Transport
2006Co-Authors: Cees D. Van Goeverden, Piet Rietveld, Jorine Koelemeijer, Paul PeetersAbstract:The pricing of Public Transport may range from charging the full price to supplying it for free. The present situation in most European countries is between the two extremes implying a partial cost recovery. In this paper we will explore both extremes on the axis of cost recovery: free Public Transport, and Public Transport without subsidies. We start with a discussion of free Public Transport, and give a short survey of the intentions governments may have with its introduction. After this short survey we discuss in more detail the experiences with free Public Transport in four real world cases, two from Belgium and two from the Netherlands: the city of Hasselt, the Brussels region (for students), the Leiden-The Hague bus corridor, and free Public Transport for students in The Netherlands. Then we discuss the other extreme: Public Transport without subsidies. We start with a short overview of the financial performance of the Dutch Public Transport systems and an analysis of the impacts of measures to improve the benefit-cost ratios. Then the effects of subsidy suspension in the Netherlands are estimated by developing two scenarios that describe opposite extremes in the hypothetical situation that no subsidies are granted to Public Transport operators and comparing the outcomes with a reference scenario where continuation of subsidies is assumed. The paper concludes with a discussion of the merits and problems of both pricing policies: free Public Transport and Public Transport without subsidies.

RELIABILITY OF Public Transport CHAINS
1999Co-Authors: Frank Bruinsma, Piet Rietveld, P. Peeters, D.j. Van VuurenAbstract:This article investigates reliability as far as the quality of Transport provided by various Public Transport modes is concerned. The reliability of Public Transport chain travelling times is examined. Up until now, research conducted in this field has only concentrated on trip reliability. A sample of 300 Public Transport chain journeys operationalised at three different times of the week (at peak hours, off-peak, and during the weekend) were looked at in conjunction with the relevant official timetables as published by the respective Public Transport companies. The distribution of arrival and departure times, specified for each Public Transport mode, was used to simulate what could be construed as travel time disruptions when compared to the official schedules published by Public Transport companies. Finally, a sensitivity analysis was used to study how different policy measures can actually serve to improve travelling times and reliability where Public Transport chains are concerned. (A)

Unreliability in Public Transport Chains
1999Co-Authors: Frank Bruinsma, Piet Rietveld, D.j. Van VuurenAbstract:In this paper the reliability of travelling by Public Transport modes is investigated. We deal with the reliability of travel times in Public travel chains. Until now the only research in this field has been directed towards the reliability of trips where only one move is made. Therefore, a new element of our approach is that the probability that passengers miss the connection from one part of a chain to the other is taken into account.We use a sample of 300 journeys by Public Transport chains and operationalise them for three different periods of the week (peak hour, off-peak and during the weekend) according to the official time tables as published by the Public Transport companies.We use the distribution of arrival and departure times - specified for each Public Transport mode - to simulate disturbances of the travel times compared to official travel times as published by the Public Transport companies.

Suspending Subsidies for Public Transport: Impacts on Public Transport System in the Netherlands
2020Co-Authors: Cees D. Van Goeverden, Paul PeetersAbstract:The paper deals with the question of how the suspension of the subsidies for Public Transport operations in the Netherlands would affect the Public Transport system. Today, the costs of Public Transport far exceed the revenues, particularly in urban and regional Transport. The most efficient measures for improving the financial performance are reducing the wages and increasing vehicle speed, for instance by enlarging stop spacing. In order to find the effects of suspension of the subsidies, two scenarios are developed describing opposite extremes that define probable developments in Dutch Public Transport. In both scenarios, suspension of subsidies would have strong negative effects on the urban and regional Transport supply. The level of service would decline and fares would increase substantially. As a consequence the demand would fall. Long distance Transport might be less affected. The effects might even be positive, depending on the strategy of the operators.
